Jonathan (Jaz) Jazwinski holds a Bachelor of Science Degree in Mining Engineering from The University of Arizona.  He began his career with SRK Consulting in 2003, as a Field Engineer on the BHP Closure Project in San Manuel, Arizona. 

With copper on the rebound, he moved on to Freeport-McMoRan’s Sierrita Operation, working as a Mine Engineer and Mine Operations Supervisor.  He had the opportunity to work in a variety of roles including construction and demolition projects, mine planning and in leadership.  In 2011, he was promoted to Chief Mine Engineer and then Mine Operations Superintendent at the Bagdad Operation.

Continuing his upward career path, Jazwinski was then transferred and promoted to the Morenci Mine as Mine Planning Manager in 2015.  He quickly advanced to Mine Operations Manager in 2016 where he and his team lead 1,100 employees at the largest open pit mine in the United States in terms of annual production.

Born in Phoenix, Arizona, Jazwinski attended Brophy College Preparatory where he excelled in Math, Chemistry, Physics and English (writing).  Outside of school, he played guitar, was active in mountain biking and developed his love and passion for weight training which continues to this day.  He met his wife, Eva, at The University of Arizona and they began their married life together in Tucson in 2006.   While living in Bagdad, they were blessed with their two children Jenna (9) and Jacob (6).  In September 2020, Jazwinski became the Mine Manager at Barrick Gold's Cortez operation in Nevada.
